My Galaxy S5 is answering itself. It doesn't ring, just answers and does not actually connect the call. While I am trying to speak to nobody, the caller is still hearing ringing on their line. When I press the "End" button, they are sent to my voicemail. To answer, I have tried a factory reset and do not have the auto answer feature turned on. I just got this phone about a month ago. SOMEBODY HELP!!!!!
